VS 2008 Scroll Multiple Listboxes Simultaneously?
Apr 16, 2009
I have three listboxes with vertical scroll bars. I'd like it so that when one is scrolled, so are the others. However, I can't seem to find a "scroll" event. I tried this:
vb.net
Public Scrolling As Boolean
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
If e.Button = MouseButtons.Left Then
[code]....
It works when you click and drag on the listbox area where the items are, but not when you click on the scroll bar!

I'm writing a program which gets the time and date from forums which only show "x hours ago" on the main thread list.What I do is get a list of threads, open their print version and fetch the info.I'm currently using a single webbrowser, because there's no control array anymore. This makes the proccess very slow.Is there a way to open all the threads' print versions simultaneously?(BTW, I'm using DOM functions like GetElementsByTag, so I'll need to get the page's "Document" object.)

I used different backgroundworkers to instantiate some 'heavy' forms thinking that it will reduce the time to instantiate them if I did them at once but it looks like I am wrong since it is still taking about 43 seconds to load all of them. Am I missing something or do you have a tip on how I can speed up their instantiation?

Not wanting to hijack 45minutes thread, I thought I might spawn a thread of my own based on his question.
PlausiblyDamp was kind enough to provide some generic code, which I have modified and attached.
I have made a few alterations mostly around removing random objects, as the game in question (Space Invaders) has a set amount of aliens and set starting positions.
As a start I have limited the UpdatedPostion to horizontal movement as the aliens only go side to side unless they hit an edge.[code]...

I am creating a GUI that monitors the entered application and if the application crashes the GUI starts the application back up. Problem is to run this application (WoW Private Server) I need 3 running applications. Is there a way to shell and wait 3 applications all at once. OR if i was to create a separate console application who's only job was to start the three applications at once how would I pass the application variable?
Here is my program thus far: [URL]

We are looking to design a security application that does the following on laptops:If the ethernet adapter is used (cable plugged in) disable/block all other network connections (wireless WIFI, mobile broadband (PPP), virtual VPN adapters etc)When ethernet adapter is not being used again, all connections allowed.We have looked in the WMI a lot but there are no good ways of doing this. Only disabling the network connection is not secure enough because most mobile broadband applications try to re-establish the connection. This should be an application that works on all laptop vendors without any user interaction (such as choosing interfaces etc..).

I'd like to allow the user to select up to an entire column of cells and type and/or paste a single value that would then change the value of all the selected cells in the DataGridView to the value that was typed or pasted. I understand this is probably two separate answers, but perhaps if there is a way to set the contents of the clipboard with the value typed, I was thinking it may work well to identify both things I want to do.

I have been using the My.Computer.Audio.Play method for sounds in my program for a very long time, but now I have reached a point where the program needs to be able to play more than one sound at a time. What is the best (and preferably simplest) way to do this?

I want to play multiple sounds simultaneously from My.Resources in Visual Basic 2010. I have tried:My.Computer.Audio.Play(My.Resources.SoundName, AudioPlayMode.Background)
I have also tried using multiple Windows Media Player controls, but that also didn't work.The first sound is cut off when the next sound plays.When searching around the internet I found people suggesting using 'DirectSound', but there are only tutorials for DirectSound in VB 6.0.

Consider I have a shared function:Public Shared Function CalculateAreaFromRadius(ByVal radius As Double) As Double
[Code]...
If I have two or more threads in the same vb .net app and each of them calls the shared function at the same time with different RADIUS, will they each get their own AREA? I want to know for each call to the function if it is using same local variables or each call creates new instances of local variables?Will the answers to above questions be same If I have multiple (2+) single threaded apps and they all call the function at the same time with different RADIUS value?

Using Visual Basic in Visual Studio 2008, I have created a Windows form with multiple tabs and questions. Each question has an associated drop-down listbox that the user will eventually click on to enter his or her response. My client has now informed me that she wants to change the standard responses in each response box. There are well over 100 drop-down listboxes, all with the same items, and they all must be changed.
I originally inputted the items using design view. Would someone please tell me if it's possible to edit all of these boxes in the design view simultaneously? When I control + click on more than one box, the Edit Items option that is normally available disappears. Is there a way to do it in code in a manner that would save back into design view?

I've created a two-worksheet template in Excel - the first sheet is for pretty charts, and the other sheet is for the data that drives those charts. I've written a vb.net 2005 app that can dump in all my data on the second worksheet, and the chart worksheet updates perfectly.I would like to do this report several times over in the same workbook. (So the tabs would read 'Person1 - Chart', 'Person1 - Data', 'Person2 - Chart', 'Person2 - Data', etc.)
My solution was to, for every person this report was going to be run for, copy the chart template, and then copy the data template. The problem is that every chart template that is created points to the original data worksheet. How can I set what worksheet each chart worksheet is pointing at?

I have two unrelated databases and I need to pass data back and forth between them. Right now I have created two separate entity models - one for each database - but this is causing issues in my code b/c I have to do a Using nameofcontext / End Using and when I try to then use some of the results from the first section of the code in a second Using nameofcontext / End Using it doesn't like it - b/c I've closed the connection to the first database!

I have four list boxes, side by side. I've got a huge list of files that the program scans through and if (file insides) = (this) then; else if and etc. I know that part is working. The problem is actually the list boxes themselves. The reason I know this is:
I have four listboxes side by side, only the first one shows data, but if I delete the first one from the form, only the second will show data, if I delete first and second, the third one displays data, and if I delete the first three, the last one shows data. The problem is they wont display data at the same time. I was talking with someone else and they said I needed to change the IDs and I should see that option somewhere near the "Name" section. I use Visual Studio 2010... I don't see any IDs option to change. on how I can change this ID or maybe something I have to do to get these listboxes working?

I am pretty sure that I understand what needs to be done here but I'm not 100% sure on how to go about this.I have a list box that contains a list of url's for websites. 100 to be exact.I have a web request defined in a private sub.What I need to do is to loop through the listbox1, grab one url, place it into the variable of the request and then save that entire web request (with link) to string.In the end I will have all 100 url's put into their own web requests and feed back into an array which I can then put into some sort of multi-threading method.

I'm writing an application in vb.net 2008. It's basically a randomised image quiz. I have saved questions, answers and time taken to answer questions into 3 listboxes: listboz1, listbox2 and listbox3. I'm trying to add the content of all into a csv file. This is my code below which only saves the contents of one listbox to a txt file. How do I get a combination of all listboxes in the file with format (L1,L2,L3)? I alos want to add the user name and the date the test/ quiz was taken.

I am compiling a quiz, so the question number, user response and time taken to answer questions are sent to 3 listboxes. I wanted to save the file name (from the login form, date and listbox contents to a text file. I have scoured numerous codws...none of them work..all with errors. I have tried to look at Streamwriting listboxes. But can not find a way to add multiple listboxes to one text box. Actually none of the codes (including the Sub SaveToKnownFileWithDelimiter (below) I have looked at work.
This is my quiz code so far....

I am new to vb and I am having so much trouble with this. What I need to do is this: I have a form application for winter sports equipment rental.I have a listbox filled with the equipment for the user to choose from then I have a combobox for the user to select the duration they would like to rent it. The book that I am using has no examples I can refrence and i have had no luck online either. I am posting what I have so far. However, i think I am going in the wrong direction. I have been working on this for so long that I think I have over thought it and made a mess of it. I am thinking that I need to add a new class for rentalRates then use enum of durationType and equipmentType but I am unsure how to move that way. That is using a enum, a 2d array and a parallel array? [code]
